Studies on the sex ratio among the flowers of Begonia semperflorens and the possibilities of influencing it with the aid of growth substances


, : Studies on the sex ratio among the flowers of Begonia semperflorens and the possibilities of influencing it with the aid of growth substances. Gartenbauwissenschaft 36(6): 483-489

Breeding lines of B. semperflorens with different genotypical tendencies for feminization of the male flowers were treated with Ethrel, GA3, IAA, NAA, MH or 2,4-D at various concentrations. However, none of the growth substances had any significant effect on sex expression.
